Effects of 2 on the cell viability of the MCF7 cell line. Different concentrations of 2 (0.5; 2; 3 and 4 μM) were combined with the IC50 of the chemotherapeutic agents a irinotecan, b tamoxifen, c cisplatin, d 5-Fluouracyl and e doxorubicin. Cell viability plots represent the mean ± standard deviation of three independent replicates with five replicates
